Morning!
I wanted to share a recent journey I took into Docker running on Ubuntu. Today, I’m going to show you how I installed Docker on my system and got it ready for creating containers.
I even show you how to create a test container to confirm you’ve done everything right…
1 First things first is to setup the apt repository:
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
2 Now we need to install the latest version of Docker:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
3 Finally, we can confirm that Docker was installed successfully by creating a test container:
sudo docker run hello-world
The above command downloads a test image and runs it inside a container. If everything works correctly, you will see that it prints a confirmation message and then exits.
And and simple now you know how to do it!
Enjoy 🎉
